To all when it may concern;

Be known-that I, CHARLES S. SIIALLF.N' BnneER, aeiti'zen'of the UnitedStates,-residing at StgLLouis, Missouri, have invented a certain anduseful Improvement in Draft-Riggings for Railway-Cars, of which" thefollowing is'a full, clear, andexactdescri )tion, such as will enableothers skille in t e 'a'rtto which itappertains to make an use; thesamarelference being had to the accompanying'flrawings; forming part ofthis 'lhisinveritidi'i re .es'to draft l'iggings, and particularly toe-drawbar yokes used in tandem draft riggings.v

One object-of my invention is to provide a yoke that is composed of anumber of independent sections which are detachablyconneoted together sothat a new section can be substituted for a broken section and thusovercome the necessity ofdiscarding the en. tire yoke in case anyportion thereof breaks. And another object of my invention is to providea cast metal yoke for tandem draft riggings which is stronger than theyokes that have heretofore been in use.

Briefly described, my invention consists in a yoke composed of a number.of separate sections or members arranged in'longitudinal alinement witheach other and detachconneeted together. y the'preferred form of .myinvention, as hereinshown, the sections of the yoke are approximately.Ushaped, and each section has a portion that interlocks with anadjacent section so as'to enable the sections to be takeh apart andassembled easily. The first section of the yoke is connected to'thedrawbar and the other section or sections are arranged one behind theother in longitudinal .alinement with the first section, the cross websof said sections cooperating with the followers of the draft rigging andthe legs of said sections embracing said followers and theshock-absorbing elements of the rign A yoke ofthe construction abovedescribed greatly reduces the cost of maintaining draft riggin 's owingto the fact that the entire yoke does not have to be dlscarded -in caseany portion thereof breaks.

Fi urel; of the drawings is a side eleva not View of adraft riggingconstructed in iccomancej'withmy invention; Fig, 2 1s a ileriri pe lynhofiz n l vs c .of said draft rigging; Fig. 3 is a perspective view ofthe yoke; and Fig. 4 is a perspective view of a yoke of slightlydifferent constructionfrom the one shown in Fig. 3.

Referring to the drawingswhich illustrate a draft rigging-that comprisestwo setsof omen springs orshock-absorbing elements, 1 designates thesprings or shock-absorbing elements.-each of which is.arranged between afront follower 2 and a rear follower 3 which cooperate with lugs orstops-on-cheek plates 4, as shown clearly in Fig. 2. v

My improved yoke is composed of'a plurali t y of separate sections ormembers which are substantially U-shaped'and arranged in longitudinalalinement with'each other, the front section A being connected to thedrawbar 5 by fastening-devices'6, and the rear section B beingdetachably connected to-the front section A. The front section ispreferably provided with lips7 which interlock with lugs on the'drawbarso as to reduce the shcaring'strains'ou the fastening" dex'ices 6, andthe rear section B is provided with lugs, or extensions 9 that projectinto slots or pockets 8 in the rear end of the section A. A fasteningdevice 10 is preferably passed through the rear section B and theportion of section A which said rear section embraces so as to hold saidsections in longitudinal alinement with each other and also into thenotches 8 in the front section A, re-' ceire some of the shocks andstrains to which the cross web of the section A is subjected and thusreduce the liability of said cross web being sheared off or broken andthe fastening device 10 that passes through'the sections reduces theshearing st-rains on the extensions 9. v

In case one section of the yoke breaks it is not necessary to discardthe-entire yoke for anew section can be'substituted easily for thebrokensection and thus repair the yoke at approximately one-half the cost of aonepiece metal yokeof the kindheretofore n use' i If desired,the crosswebs of the sections A and B can be provided with curved faces 11 asshown 'in Fig. 2 so as to permitthe draw-bar to swingor rock while thecar is going around curves.

In Fig. 4- I have illustrated a slightly modified form of my inventionwherein the rear section B of the yoke is provided with lips orprojections 9 having concaved inner edges which conform to the concavedbottom walls of the slots 8 into which said lips project, the legs ofsaid rear section B also being'provided with concaved faces 12 thatengage convexed surfaces on the front section A, as shown clearly inFig. 4 With such a construction it is not necessary to connect thesections of the yoke together by means of fastening devices as theshocks to which the yoke is subjected when in use do not tend to makethe sections rotate relativelyto each other. In assembling the parts ofthe yoke shown in Fig. i the lips or extensions 9 011 the rear section Bare partially inserted in the slots 8 and one section of the yoke isprising two substantially U-shaped members arranged in longitudinalalinement with each other and with their legs projecting in the samedirection, the cross web of the front member being provided with slotswhose bottoms are convexed, and lugs on the rear member that projectinto said slots,.the lower ends of said lugs being concaved so-that theywill'conform to the shape of the bottoms of said slots.

In testimony whereof I hereunto 'aflix mysignature in the presence oftwo'witnesses,

this twenty-fourth day ofvOctober 1908.
